BUFFlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 693,912, dated February25, 1 02- Application filed January 11, 1901. Serial No. 42,859. (Nomodel.) I

To aZZ whom it may concern.-

Be it known that I, JOHN M. SELLMAYER, a citizen of the United States,residing at Rochester, Monroe county, New York, have invented anImproved Buffing-Machine, of which the following is a specification,reference being had to the accompanying drawings.

My invention relates to an improved con struction of buffing-machines,designed more particularly for buffing the outside surfaces of hollowware, but capable of many other uses.

My improvements are fully described and illustrated in the followingspecification and the accompanying drawings, the novel features thereofbeing specified in the claims an-j neXed to the said specification.

In the accompanying drawings, representing my improved buffing-machine,Figure l is a plan view. Fig. 2 is a front elevation. Fig. 3 is a sideelevation. Fig. 4. is a section through the form and clamp. Fig. 5represents the mechanism for shifting the buffingshaft positively. Figs.6 and 7 are side elevations of the same in different positions, showingthe reversing mechanism.

A represents the revolving buffing-shaft, which carries the work orarticles to be buffed at one end and presents it to the buffer orbuifing-wheel B. The work is indicated at O, and the clamp is shown at Dfor holding the work 0 against a suitable form E on the end of thebuffing-shaft.

F, Fig. 2, is the main driving-shaft, which drives the buffing-shaft Aby means of the bevel-gears G, the upright shaft H, and the bevel-gearsI. The shaft A is so supported and arranged that while running it may beshifted lengthwise and laterally and also inclined in either directionin the horizontal plane, as indicated by the dotted lines A A A AFig. 1. Provision is also made for shifting the shaft up and down in thevertical plane by adjusting the framework, as hereinafter described.

The bufier or buffing-wheel B is of any ordinary or preferredconstruction, supported and driven on any suitable frame, and arrangedin suitable relation with the buffingshaft. The buffer and the shaft Amay revolve in the same or in opposite directions.

J J, Fig. 2, represent the side frames of the machine, which areattached to any suitable base K and connected together by any suit ablecross-bars. The driving-shaft F is jours naled in the side frames andprovided with a suitable pulley, by which power is trans: mitted to themachine. The buffing-shaft A is supported on a swinging frame,consisting of the arms L and the top or table N, arranged to swinglaterally between the side frames J J, so that by this movement(indicated by the dotted lines H H H H Fig. 3) the shaft A may beshifted bodily to and from the buffer B. Thelower end of the shaft Hrevolves in a step 0, attached to a sleeve b, fitted freely on the shaftF between the collars a a. In this way the frame L L is allowed to swingaround the axis of the shaft F, while keeping the gears Gin mesh. Thejournals 0 0 of the shaft F project into openings in bosses on the lowerends of the arms L L, so that the arms swing on the journals and not onthe shaft. The upper end of the shaft H revolves in a journal at on aplate e, attached to the top N of the swinging frame. By means ofclampscrewsf, Fig. 3, the swinging frame can be fixed in any desiredposition, such screws passing through curved slots g in the upperportions of the side frames J. Above the table N the shaft H passesthrough a boss 2, carrying the curved frame P, which supports thejournals Q Q, in which the boiling-shaft A revolves. The bevel-gears Iare placed within thiscurved frame. As the boss v is free to rotate onthe shaft H, the bevel-gears I will remain in mesh while the shaft A isshifted in the horizontal plane, as indicated by the dotted lines A A AA Fig. 1. order to permit the lengthwise adjustment of the shaft A, thebevel-gear I on the shaft is splined and its hub is provided with acircumferential groove into which is fitted a guide h, Fig. 1, attachedto one of the journals Q. The bevel-gear is thus held in proper relationwith its mate,while the shaft A may be shifted lengthwise through it.

To shift the buffing-shaft A lengthwise through its journals, thehand-wheel R is em ployed in connectionwith the threaded sleeve S. Thehub of the wheel R is provided with a circumferential groove, in which aguide j, Fig. 1, attached to the journal Q, engages, so that the wheelcan revolve without shifting laterally. The hub of the wheel R isthreaded internally onto the sleeve S. A key or spline 70, Fig. 1,prevents the sleeve S from rotating in the journal Q. The sleeve Sisconfined lengthwise on the shaft A by the collars Z Z, fastened to theshaft. The sleeve is free to slide through the journal Q. Since thesleeve S cannot turn in the journal Q and has collars Z Z at each endwhich prevent its moving lengthwise on the shaft A, it will be evidentthat turning the hand-wheel R will shift the shaft A lengthwise or inthe direction of its axis, and so will present the work to the butfer ina different position.

The manner of supporting the article to be bufied will be understoodfrom Figs. 1 and 4. E is a form of a shape suitable to fit the interiorof the article to be buffed, which form is attached to the end of theshaft A. The article is clamped by the clamp D against the outer end ofthe form. 0 Fig. 4c, is a washer, of any suitable material, which may beplaced between the clamp and the form to hold the article in place. byan arm T, mounted on the end of a rod U, which is itself supported bythe journals Q. The rod U extends parallel to the buifer-shaft A, beingsupported by the arms V V the inner ends of which are inserted in bosseson the journals Q Q, the outer ends carrying the sockets m m in whichthe rod U slides, with provision for clamping itin any desired position.The arm V is attached in a similar manner to the rod U by the socket m,its inner end being fastened to a collar n, Fig. 1, within which theshaft A revolves freely, with adjustable collars r 1' on each side ofthe same, the construction being designed to cause the clamp D to travelwith the shaft A and its form E when they are shifted lengthwise. Theclamp D and its Washer O are permitted to revolve with the article 0 bythe stem 8, Fig. 4, arranged to rotate in a socket q, secured on theinner end of the arm T, or of a socket thereon; p is a nut on the outerend of the stem 8. It is necessary to swing the clamp D out of the wayfor the insertion or removal of the article to be buffed, G. For thispurpose the arm T is pivotally con nected with the end of the rod U inany suitable manner, such as by the socket u and clamping-wheel M,threaded on the end of the rod. 1: is a collar fixed on the rod insidethe socket a, which may be provided with any suitable stops arranged tolimit the movement of the arm T and the clamp D when it is swung up ordown out of line with the shaft A and its form. The manner of applyingor removing the article to be buffed and of securing it to the form Ewill now be understood. The wheel M being unscrewed,

the arm T and the clamp D are swung out of line with the shaft A, thearticle is applied to the form, and the clamp is replaced and forced.against the article on the form by the threaded hand-wheel M or by theadjustments pro- The clamp D is supported vided in the socket m, so thatthe article is compelled to revolve with the buifer-shaft, while thearticle, the clamp, and the form are permitted to be shifted lengthwiseof the shaft to present the whole surface of the article to thebulfer-wheel B. In order to provide for conditions where it may bedesirable to arrange the rod U on either side or on top of the shaft A,the journals Q Q carry three sets of bosses 0000 in any of which thearms V and V may be inserted and secured, asindicatcd by the dottedlines in Figs. 1 and 3. The positions of the shaft U at these times areindicated by the dotted lines U U, Fig. 3. This construction providesfor locating the buffer-wheel in any desired position relative to thebufling-shaft.

In order to provide for the case when it is desired to shift the objectto be buffed more rapidly than by the hand-wheel R, I arrange to drivethe hand-wheel positively, as indicated in Figs. 5, 6, and 7. For thispurpose the counter-shaft A is employed, with a series of intermediateand reversing gears arranged so that the hand-wheel R and its nut may bedriven positively in either direction from the power of the machine at ahigher speed than can be given to it by hand. The countershaft issupported from the bosses Q Q by the arms B. The countershaft A isdriven from the burnisher-shaft A by the gears O, D, D E, and F, Fig. 6.The gear C is mounted onthe shaft- A and revolves with it. The gears D Dare carried by a movable arm G, by which either of them can be engagedwith the gear 0, so as to reverse the motion of the shaft A The gears DD are always in mesh with each other, the relative positionswhen theshaft A is running in one direction being shown in Fig. 6 and whenrunning in the opposite direction in Fig. 7. The arm G is pivoted on apin L in the bracket 13, on which also the gear E revolves in permanentmesh with the gear F on the shaft A When the gear D is in mesh with thegear 0, as shown in Fig. 6, the shaft A will revolve in one direction,while when the gear D is in mesh with the gear 0, as indicated in Fig.7, the shaft A will revolve in the opposite direction. The shaft Atransmits its motion to the hand-wheel B through the gear I, theintermediate 1 and the gear I. (See Fig. 5.) The gear 1 revolves on astud supported by the bracket B, and the gear I is attached to thehand-wheel B. Any suitable devices may be employed for locking the leverG in positions where the gears D or D are in mesh with the gear 0. If,therefore, the operator desires to shift the article to be buffedrapidly, he secures the longitudinal movement of the buffing-shaft A bymanipulation of the hand-lever G. At the same time when the lever G isplaced in such a position that neither of the gears D D are in mesh withthe gear 0 the operator can shift the shaft A by the hand-wheel R.

Any suitable means may be employed to shift the buffer-shaft A about thevertical axis of the shaft H, as indicated by the dotted lines A A A AFig. 1. In the construction illustrated the curved frame P, with its hub41, is shown as attached to the worm-gear W, operated by a worm X, Fig.5, on a shaft Y, provided with a hand-wheel Z, Figs. land 2. The shaft Yis supported by suitable brackets on the plate e or the table N, and byturning the hand-wheel Z in either direction the buffer-shaft is shiftedin the horizontal plane and the article 0 presented to or removed fromthe buffer B, as indicated by the dotted lines in Fig 1.

In order to adjust the machine up or down to vary the position of thebuffing-shaft relative to the buffer, I employ the hand-wheel and screw6 and 2, Figs. 2 and 3. The side frames J J are pivoted on one sideattto the lugs or brackets 20 on the base K. On the other side the sideframes are connected together by the bar N, Fig. 2, and the screws isthreaded through this bar, with the lower end of the screw bearing onthe base K, so that the right-hand side of the machine, as seen in Fig.3, may be adjusted up and down, thereby varying the height of thebuffingshaft relative to the bufier. The screw 6 may be provided with ajam-nut, and f is a clamp-screw for holding the frame in any position inwhich it may be set.

As already mentioned, the frame L L N and the buffing-shaft aresupported so as to swing about the axis of the shaft F, as indicatedbythe dotted lines H H in Fig. 3. A spring 0, Fig. 3, is arranged aroundthe threaded shaft P, provided at its outer end with the handwheel Q andsupported in an arm R, attached to one of the side frames J. The shaft Pis threaded into a nut S, attached to the swingingframeLLN by the pivots0,Fig. 2, inserted through a suitable bracket 2",fastened to the lowerside of the table N. It will be understood that by turning thehand-wheel Q in one direction the frame, table, and object to be buffedwill be withdrawn from the bufier, while by turning it the other way thearticle will be placed in contact with the buffer, against which it isheld by the weight of the frame. The spring 0 prevents the frame fromfalling too far to the left in Fig. 3 when the article is Withdrawn fromthe bufier.

The rod J, Figs. 1 and 2,inserted in the collar n, serves to move thebuffing-shaft and clamp by hand into any desired position.

K is a fiy-wheel on the buffing-shaft, which may also be used forpurposes of adjustment.
